Ensure uninterrupted power and protect your essential systems with this Automatic Dual Power Transfer Switch (ATS)/ Change over switch. Designed for seamless automatic power transfer between an off-grid renewable energy source (solar, wind, hydro) and a backup power supply such as a generator or the grid, this intelligent switch guarantees reliable operation during a power outage or battery depletion. Ideal for home energy systems, RVs, boats, cabins, and critical systems requiring constant electricity.

Reliable Automatic Power Transfer for Backup Energy: 

This power transfer switch automatically prioritizes battery/inverter power and only switches to grid or generator when battery voltage is low. Once the battery is recharged, the ATS instantly switches back—providing a smart switchover without interruption.

Features:

• Automatic Power Transfer: Seamless switchover between primary and secondary power sources without system downtime

• Battery Priority Mode: Inverter AC from solar/wind/hydro-powered batteries is used first; switches to generator/grid only when needed

• Rapid Transfer Times:

  • Inverter to public power: ≤ 10ms

  • Public power to inverter: ≤ 16ms

  • No flicker, no interruption—ideal for sensitive electronics and critical systems

• Energy-Efficient Operation: Save up to 30% on your energy bill by maximizing the use of renewable sources

• Battery Protection: Prevents over-discharge, extending battery lifespan and ensuring availability during emergencies

• User-Friendly LCD Display: Monitor power supply status, grid availability, battery voltage, and more

• Simple DIY Installation: Plug-and-play design; no need to cut into factory wiring—ideal for boats, RVs, and mobile setups
